L6227N

Overview

The L6227N is a DMOS dual full bridge gate driver designed for motor control applications, realized in MultiPower BCD technology. It integrates isolated DMOS power transistors with CMOS/TTL compatible logic inputs. The device operates within a supply voltage range of 8 V to 52 V and delivers an output current of 2.8 A. It features rise and fall times of 250 ns and a maximum turn-on delay of 1900 ns. Operating temperatures span from -40°C to +150°C. The component is housed in a 24-pin PowerDIP package suitable for surface mount or through-hole installation.

Feature Summary

• Integrates isolated DMOS power transistors with control logic in MultiPower BCD technology
• Provides dual full bridge configuration for bipolar motor drive applications
• Compatible with standard CMOS and TTL logic input levels

Applications

• Bipolar stepper motor control
• Brushed DC motor drive systems

Procurement Notes

Verify the specific suffix (e.g., N for PDIP) against the required package type. Confirm RoHS compliance status via the manufacturer's official documentation. Check humidity sensitivity classification and storage conditions prior to assembly. Ensure the ordering part number matches the exact electrical specifications required for the target application circuit.

Selection Notes

Select this component when a robust dual full bridge solution is needed for high-current motor loads up to 2.8 A. The integrated isolation simplifies design by reducing external component count. Consider the thermal resistance characteristics of the PowerDIP package for heat dissipation requirements. Verify that the 52 V maximum supply voltage aligns with the system power rail.
